Yes, if I read a Table of Contents;
$ tar ztvf 5_axis_kinematics_XYZAC.tar.gz
then extract one file:
$ tar zxvf 5_axis_kinematics_XYZAC.tar.gz XYZAC/README
there is no failure due to naming conflict. README is extracted without
problems.

It does. Thank you.
Now to repeat for the other 9 files. The following seems to do it (On
the command line, since something so simple isn't worth putting in a
script):
# This just shortens the next lines, so they won't wrap in the email.
$ archive=5_axis_kinematics_XYZAC.tar.gz
# "NR > 1" skips the symlink, which isn't to be copied.
$ files=`tar ztvf $archive | gawk 'NR > 1 {print $NF}'`
# Now we finally extract 'em all individually, by name.
$ for i in $files ; do tar zxvf $archive $i ; done
I still had the symlink, so the files ended up in ../emc2/configs/XYZAC/
If no previous extraction attempt had been made, they'd be in XYZAC/
in the current directory.
I'm off to the farm for a week tomorrow, so won't have much time to read
and learn. Lacking the means to try out XYZAC/XYZACkins.c, it'll even
then not be easy to offer much useful feedback.
Thanks to Rudy for doing the kinematics for a machine that I've for some
time thought would be a lot of fun to build.
